Default namespace for anonymous requests?

Is there a way to configure a default namespace for anonymous https requests?

I'm looking to host some static web content on ECS.  My understanding is that requests for public objects must either include the x-emc-namespace header in the request or have a namespace-enabled Base URL configured.  Including the extra namespace header is no good for static web content, and the namespace Base URL means I'm going to have less memorable long URLs:

Rest endpoint: s3.myco.com

URL with namespace enabled base URL:  https://mybucket.public.s3.myco.com

SSL certificates get a little hairy here too, *.s3.myco.com for authenticated virtual-host style addressing and *.public.s3.myco.com for anonymous I guess?
